21659-72-3 Usage
Explanation
The compound consists of 9 carbon atoms and 14 hydrogen atoms.
Explanation
It has multiple carbon-carbon double bonds, but they are not adjacent to each other.
Explanation
The nine carbon atoms are bonded together in a straight chain.
Explanation
The carbon atoms are connected with both single and double bonds, alternating between them.
Explanation
A methyl group (CH3) is attached to the fifth carbon atom, making it distinct from other nonatriene isomers.
Explanation
The presence of the methyl group at the fifth carbon atom differentiates it from other isomers with different methyl group positions.
Explanation
It is often used as a precursor for the synthesis of various organic compounds in research and laboratory settings.

Check Digit Verification of cas no
The CAS Registry Mumber 21659-72-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,6,5 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 21659-72:
(7*2)+(6*1)+(5*6)+(4*5)+(3*9)+(2*7)+(1*2)=113
113 % 10 = 3
So 21659-72-3 is a valid CAS Registry Number.

Regiospecific Cp*Ru+ mediated codimerization of conjugated dienes with non-conjugated 1,5-dienes and its application to catalytic cooligomerization
Masuda, Katsuyuki,Ohkita, Hironobu,Kurumatani, Shigeru,Itoh, Kenji
, p. C13 - C16 (1993)
When Cp*RuCl(η4-butadiene) (1; where Cp* = η5-C5Me5) was treated with an excess of 1,5-hexadiene in the presence of silver trifluoromethanesulfonate (AgOTf) at or below ambient temperature, a 2-(3'-butenyl)-1,5-hexadiene complex of cationic ruthenium was obtained by regiospecific C4 homologation at the internal carbon atom of the non-conjugated diene.This stoichiometric C-C bonding was extended to the catalytic codimerization and stepwise oligomerization of butadiene with 1,5-hexadiene or 1-hexene.
